Groenland
In short
Greenland is the world's largest island and an autonomous territory within the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of Canada.
In plain words
It is a massive, icy land located near the North Pole. While it belongs to the Danish Kingdom, it manages its own local affairs. Most of the island is covered by a thick ice sheet.
A simple example
A person born in the capital city of Nuuk holds Danish citizenship and can travel using a Danish passport.
Why it matters
Its vast ice reserves and strategic location make it vital for studying climate change. It also holds significant importance for global shipping routes and natural resources.
Easy to mix up
Do not confuse Greenland with Iceland, which is a separate independent nation located to the south.
